Specification of Letters Patent.

Application filed June 29, 1916. Serial No. 106,582.

To all whom t may concern.'

Be it known that I, EDWIN F. BEUGLER, a citizen of the United States, residing at Bualo, in the county of Erie and State of New York, have invented new and useful Improvements in Machines for Cutting Ends of Barrel-Shells and Removing Hoops Therefrom, of which the following is a specification.

This invention relates to a machine for operating on the ends of the bodies or shells of barrels preparatory to applying the heads thereto, and more particularly to a machine which cuts the ends of barrel shells and also removes temporary hoops therefrom preparatory to applying the permanent hoops and heads to the ends of the shells.

It is the object of this inventionto pro# duce a machine which will accomplish this purpose automatically, economically and eX- peditiously with an expenditure of a minimum amountV of manual labor and power.

In `the accompanying drawings:

Figure l is a fragmentary perspective view of one of the staves of a barrel shell or body in its finished state after the ends thereof have been `operated upon by the machine forming the subject of this invention. Fig@ is a front'elevation of the machine embodying my improvements, showing part of the frame broken away. Fig. 3 is arear elevation of the same. Fig. 4 is an end elevation thereof viewed from the left hand end. Fig. 5 is a vertical transverse section of the machine taken on line 5--5, Fig. 6, and looking toward the `lefthand end of the machine. Fig. 6 is a top plan view of thek machine showing the feed belt in dotted lines. Fig. 7 is a transverse section of the machine taken on line 7 7, Fig. 6. -Fig. 8 is a vertical longitudinal section of the machine taken substantially on line 8-8, Fig, 4:. Fig. 9 is'a sectional perspective view of the cutter head or holder carrying the blades for crozing and. chamfering the barrel staves at one end of the barrel shell. Fig. 10 is a fragmentary side view, on an` enlarged scale, of the means for shifting Aone ofthe end trimmers into and out of its operative position. Fig. 11 is a fragmentary view, on

areduced scale, showing the mannerinv which the shell carrier retains one of the shells in its operative position relative to l `the centering chucks and the cutter mechaet' nisin associated therewith.'

Similar characters of reference indicate corresponding parts throughout the several views.

l represents the staves of the body or shell of a barrel which is adapted to have opposite ends of its staves operated upon by the improved machine forming the subject of this invention for the purpose of preparing this shell to receive the heads and the permanent end hoops. In the operation of this machine the opposite ends of each stave thereof is provided with transverse crozes 2 on its inner side, chamfers, or bevels 3 between these crozes and the ends of the stave and transverse ends faces 4 at the outer ends of the chamfers, as shown in Fig. l.' Before the barrel shell is place-d in the machine for performing the crozing, chamfering and end trimming of its staves a pair of permanent hoops 5 are applied tothe central part of the periphery of the shell on opposite sides of its bilge, and a pair of temporary hoops 6, preferably of iron, are applied to the periphery of the barrel adjacent to opposite ends thereof. In the operation of the ma- -chine the attendant places a barrel body or shell of this character upon a suitable track or guideway in position to be engaged by a carrying mechanism which moves this shell successively to the means which produce the crozes, chamfers and end trimmings thereon,

then to a mechanism which operates to re-` move the temporary barrel hoops from the shell and then discharges this shell from the machine ready to be assembled with previously prepared heads and which latter are retained in place by permanent hoops applied to opposite ends of the shell.

7 represents the main frame of the machine which may be of any suitable construction to support the various working parts of the machine.

8, 8 represent two head stocks arranged transversely and in' an upright position above opposite ends of the main frame so that they are in axial alinement lengthwise of the machine. On its inner side each head stock is provided with an internal annular guide groove 9 which receives a rotatable chuck ring l0 adapted to receive one end of the assembled shell or body of the barrel and engage frictionally with the periphery thereof so that upon rotating the chuck rings ofboth head stocks the barrel shell will be turned about its horizontai axis. While the barrel shell is thus arranged between the head stocks preparatory to being chueked or centered thereon and *also after f the head stocksarewithdrawnpreparatory to removing the shell after the work upon ythe same has'been'completed, the 'barrel shell is supported between the head stocks by means f a track or `1guideway comprising `two guide rails 11, 1l which are arranged horizontally and transversely above the central part of the inainfrainebetween theftwo hea d stocks. -Vertically in line-with the eentersof the head stocks and the chuck rings and in a lplane *lengthwise of the --machine the Iupper edges .oty theguide rails -areprovided with center- Aingvnotehes 12, V1 2A preferably' of V-shaped form,- afs-'shown in-Eig.-7, which notches term lseat-sin .which-the lower sideofthe barrel "shell `vrests 'uponl reaching the cutting i position of the maohineandtherebylaid in center-ing 4 the;` barrel shell or body preparatory to=perior1ningfthecutting operations on the same. Theseguidc rails may be supported ilrany--suitablemanner, butiasshown in the Adrmv-i1-igs the same are supported on their Outersides by means of brackets Y 13 proj ectinglaterallytherefrom, clips or clamps 14e carryingsaidbraeketS, and i'rontland rear columnsor posts 15, lwhich 'are secured at theirHlo-werfendstothe fro-nt and rear parts of theemain'rameandto which the clamps 14 fare secured in such manner that the fsame maybe adjusted Yvertically Aon the supporting -posts for the purpose fof bringing- =the guide rails -into the proper position relati vel'y to the head ystocks for. guiding Ythe barrelfsjhells .to and from the cutting position. On .the `front side of thevmachinetwo rend guidebars 17,-171are arranged horizontally and ltransversely vrelative to the direction of movement otthebarrel shell to themachine, which endguidefbars are adapted to engage oppositeendsoi: the barrel shellandy cause the same to enter;properly/between the two head stoekspreparatory to n elfecting the centering ofthe barrel-shell and the cutting o'fopposite fend-s of its staves These 'front end guides are spreferably adj ustably supported by--means of clamps or clips 1S, 18 ou the upper :parts of the front :supportii'lg posts` 15 whichzcli-ps- (1i-clamps arecapable of vertical adjustment on the latter in. order to bringthe samelinto-theproper position relativegtothefbarrel shell and the head stocks. Onthe-rearsideoi' the machine the vsame is also provided withtwo frear end guides 19, 19 which are'adapted -to engage with opposite ende toflthe barrel shell andeonfine the samefagainstmovement in the direction voit its length while'on the guide railsfand therebymet-ainthe shell always in 1 a position where the saine can be operated -u-pon =by other mechanism and* lalso `be Vconveniently removed by the attendant. The rear end guide bars are preferably so constructed that they serve as end guides just before the shell reaches the rear end of the guide rails at which time the means which'remove the temporary barrel hoops perform'their operation,

moved -endw-ise fromV the supporting rails.

For this purpose each of the rear end guide bars has a horizontal `irontupperpart `20 wh-iclris arrangedon one` side ofthe companion supporting 4rail and in a higher plane, while the rear -part 210i this end guide barinclines downwardly and v'crosses thet plane-:of the-companion guiding or supporting rail at la point infront-of the rear end1` of theflatter, as shown iirFigs.

After the. operator. vplaces ia' barrelfshell on wthe 4front parts of the supporting A rails the sameis feng-aged by la carrying-or propelling mechanism `which#moves `this shell successively to y the stave 1 cutting, hoop Lremoving and discharging positions., Although this carrying mechanism may be constructed in various wvays rthat yshown 4in the drawings has been lfound suitable in =`practice and therefore i preferredand :as there shown =-the sameis constructed;-asfollows: Y

l24, 125 -represent front l and Jrear sprocket wheels -1 arranged adjacent to the vfront and rear; sides offthe main frame*` transversely in line xwith the space between `the fopposing head stocks.. These -sprocket wheels *are mounted on front and frear shafts Q6, 27 which are journaled horizontally and lengthwise .in suitable lbearinfgs onthe adjacentipartsoi themain frame. Around these sprocket wheels passes a `carrying belt `28, preferablyof the chain type which ychain passes with its :operative stretch 'over Athe upper central part of -the `main' `:trame and below the Aspaoe between the supporting rails. An intermittentrotary movementus imparted `to `the sprocket wheels -so las to cause gther carrying belt Yto ladvance one step at `a time land movethe barrel shells or bodies which arelplaoed on lthe'frontparts of --the supporting rails successively uto the stave cutting-and hoop removing positions and `then discharging the barrel .shell from the machine. VUnie-various means Amay `be provided -for 'effecting vthis step by step movement-oit' `the sprocket `wheels and chain beltthos'efshown Yin Figs. 3, 5, 6, 7 and 8 :are satisfactory Aand comprise .a ratchet wheel 29 secured to the rear shaft 27 which also 32 pivoted by means of a pin 33 on the lower part of a main frame so as to swing in a vertical plane, a link 34 connecting the rear arm of this rock' lever with the lower arm of the ratchet lever, a rotatable cam 35 arranged in the lower part of the main frame and engaging with a roller 36 on the front arm of the rock'- lever 32 for the purpose of depressing the same andcausing the ratchet lever to move the ratchet wheel and the parts associated there-- with forwardly one step, and a spring 37 bearing at one end against a shoulder 38 on the main frame while its opposite end bears against a shoulder 39 on aV pull rod 40 connected with the front arm of the cam rock lever so as to turn the ratchet lever backwardly in position to engage its pawl with a new tooth of the ratchet wheel. In order to avoid breaking any parts of this feed mechanism in the event that a barrel shell becomes stuck in the machine asafety device is provided which is capable of yielding when subjected to undue pressure. For this purpose the rear arm of the cam rock lever is constructed of an inner section 41 which is formed on the hub of this lever, an outer section 42 pivoted by means of a pin 43 to the inner section, a yoke 44 bearing against a seat 45 on the inner arm section 41, springs 46 each bearing at one end against a shoulder Y 47 on the yoke and at its opposite end against a shoulder 48 on the outer arm section so as to yieldingly hold said arm sections in theirv mit the movement of this lever under the action of the cam 35- to the ratchet wheel 29 and the parts associated therewith when no undue resistance is offered as is the case when the `barrel shell moves freely forwardly between the head stocks under the action of the carrying belt. But if the barrel shell should become stuck in the chucks or if its forward movement is obstructed in any other manner which would be liable to break or derange parts of the machine such undue resistance to the forward movement of the carrying belt would cause the springs 46 to be compressed and permit the cam 35 to complete its rotary movement without actuating the ratchet wheel and thereby avoid breakage or injuryto the machine. The instant the machine isagain cleared so that no interference with the forward movement of the feed belt exists the springs 46 automatically return the inner and outer sections of the cam rock lever to their normal operative position so that no ,manual attentionis necessary for this purpose.

j The cam 35 which operates the barrel pro pelling chain belt is mounted on a cam shaft 51 arranged lengthwise and horizontally in the lower central part of the frame and journaled in suitable bearings at opposite ends of the latter. On the upper central part of the main frame and journaled lengthwise in suitable bearings thereon is the main or driving shaft 52 which may receive its power from any suitable source, but which, as shown in the drawings is preferably driven by means of a belt passing 4around adriving pulley 53 fixed on this shaft, a loose pulley 54 being provided on the latter to receive the driving belt when it is desired to stop the machine. Motion is transmitted from this driving shaft 52 to the cam shaft 35 preferably by means of an intermediate or counter shaft 55 journaled lengthwise and horizontally in suitable bearf A ingson the main frame between the main shaft and the cam shaft and provided at one end with a gear wheel 56 which meshes with a gear pinion 57 on the main shaft and also provided with a pinion 58 which meshes with the gear wheel 59 on the cam shaft,`as shown in Figs. 6 and 8.

The barrel bodies or shells are compelled to move forwardly with the carrying belt while resting on the supporting rails adj acent to the upper operative stretch of this belt by means of a plurality of pairs of wings which are mounted at intervals Von the carrying belt, cach adjacent pair of wings being adapted to receive a barrel shell or body between them and carry the same forwardly over the supporting rails. rlhese carrying wings may be mounted on the carw rying belt in any suitable manner so that the saine may be adjusted'relatively to each otherto suit the diameter of the bilge of the barrel body or shell which is being operated on. For this purpose each wing comprises a rear arm or jaw 60 pivoted at its inner end on one of the links of the feed chain, a brace 61 pivotally connected at its outer end with the outer end of the arm 60 and pivotally connected at its inner end with a link of the feed chain in advance of the arm 60, a front arm or jaw 62 pivoted at its inner end to the inner part of the brace 61, and an ad justing lug 63 arranged on the rear side of the front arin62 and provided with a curved slot'64 which receives a clamping bolt 65 on the outer part of the brace 61. By this means each rear arm is connected with the feed belt in such manner that the same is free to pass around the turns of the belt while on the sprocket wheels without bind ing or cramping and each front arm is also operatively"associated with the front arm of the' next following wing in such manner that said wingarms may be readily adjusted relative toeachotherlfor 'adapting the space between the cooperating wings to suit the particular bi-lge diameter of the barrel shells or tbodies intended to be received between them.

Arrangedflengthwise in the upper' part of the frameand'parallel with veach other are two horizontal sliding bars or `rods 65, 66, thesefbars being Vsupported andguided in front and rearlugsa, 66L on theupper part of then'ain frame so that they are capable of sliding horizontally therein. Each ofthe head stocks is normally rigidly connectedwith one ofthe sliding hars so as to niove"'lengthwise therewith butthe saine is slidably mounted on theother sliding bar so'that 'upon"a"djusting the head stocks'toward Vand fromeach vother the sliding bars slide lengthwise of the machinein opposite directions on the'main frame but Vmaintain the latter always in axial alinement. The right `-h and head stock is preferably connected rigidly withtherear sliding bai-66 so-'as to movelengthwise therewith but slides lengthwise-on the front lsliding bar, 'while the left hand'head stock isrigidly connected with the `front sliding bar 'and isslidable lengthwise on'the rear slidinglbar 66. For this purpose the righthand head stock is provided with a rear supporting sleeve 67 which is split and has its parts clamped against opposite sides of the rear sliding bar by means of bolts 68 and with a front sleeve 69 'which yis free to slide on the front sliding bar, as shown in Figs. 5 and 7. The lefthand head stock on the other hand is provided with a split front sleeve 7 Orwhich has its parts clamped against opposite sides ofthe frontV sliding bar 65 by 'means of belts 71 lwith arear sleeve 72 which slides on the rear sliding bar, as shown in Figs. 2 and Upon loosening the bolts 68, 71 of the sleeves 677 the head stocks may be adjusted lengthwise relatively te each other on the front and rear sliding bars for the purpose of adapting the machine for operating `on barrels of varying length.

While a barrel shell 'or 'bodv is being moved rearwardly overthe transverse guide rails 11, 1l, the head stocks are moved lengthwise apart froin'each'other and when the barrel `shell reaches the cutting position the two head stocks move toward each other so that the chuck jaws or conical surfaces 73, 73 on the opposing sides of the chuck rings engage with 'opposite ends of the'barrel shell and not only center the latter but also grip the saine so that it is coinpelled'to turn with the chuck rings preparatory to performing the cutting operations on opposite 'ends of the shell. This longitndif nalinovement ofthe head'stocks and asso,-

ciatcd parts for `chucking"and releasing a barrel shell may be effected" automatically by variousinc'ans but preferably bythose which are shown in the drawings and which are constructed as follows:

74, 7&1- represent twof substantially U- shaped yokes each of which is arranged diametrically across the outer side of one of the hea'dsto'cks and"'pii`1otallyV connected at its opposite ends bytransversepivots or bolts 75 to the "outerside ofA therespective head stock soas to be' capable ofswi'nging in a substantially' verticalf'plane relatively thereto. Each of these ykcs'is-provided with a horizontallongitudinal shifting rod 76 which isprovid'edhvith aneXternal screw thread and is' arranged substantially in Eaxial alinement *with "the respective head "stock Yand chuck ring. 77, 771iepre`sent two uprightv chuck levers' which are pivoted on`s`uit- 'ablebrac'kets 78,78n1ounted on'the opposite'fendsof the main frame and each of whichis pivot'ally and adjustably connected "atits upper end with theI threaded shifting rod 760i' one ofthe head 'stockyoles This connectioinasbest'shoivnin'lfigs, 3, 4, 6 and 8, `preferably comprises 'a coupling or adjustinof sleeve 79 mounted on the respective shifting rod 76 and connected on its undersideby ahorizontal transverse pin 80 with the upper end'ofthe adjacent chuck lever 77 andsciewnuts 8l, 82,arranged'on theshifting'rod 76"`and engaging "with 0pposite endsof the coupling Vsleeve '79. Upon tightening ne f the/screwnuts and loosening the "other the respective `'shifting rod may be adjusted:'relzitivelyi toi the companion chuck lever i'norderto suit the position of the correspondinglh'eadstock on the sliding bars in a direction lengthwise L of the machine. Onfits lo'werarm each of the" chuck levers `is provided with a 'roller 83 which engages 'with the groove Sil-of the cam 85 mounted on `the `adjacent e'ndof the cam shaft 51,a`s shown in Figs. V2 fand 4. The cams 85, 'are soldelsi'gned 'that when the machine vis in operation it will iturn the chuck jlevers so asto move the head lstocks and associated parts jawayfromeach-or into tli'eir inoperative position while barrel shell is 'being' movedv forwardly 'between the head `stocks Aand after this barrelV shell reachesthe cutting'position the head stocks will be moved siinnltaneously :toward each other-and canse theawsof the chuck rings to grip opposite ends lofthe barrel shell.V

After -the chuck rings have 'been "applied to opposite ends of the barrel shell the latter is turned withthese rings owing to the lfact that the latter duringthe normal 'operation of themachine 'are rotated continuously in the direction ofthe arrow 86 in Fig. 7. The means whereby this rotary movement is imparted to the chuck "rings preferably `com `prises gear rims or teeth 87 formed on the peripheries of the chuck rings and engaging with driving gear wheels 88 each of which is splined on the driving shaft 52 so as to be compelled to turn therewith but be free to slide lengthwise thereon. Each driving gear wheel 88 is however, compelled to move lengthwise of the machine with its companion head stock but free to turn transversely relatively thereto by means of two retainingjaws or bearings 89, 90 arranged on the lower part of each head stock and engaging with opposite sides of the respective driving gea-r wheel 88, as shown in Fig. 8. By this means the driving gear wheels 88 are compelled to move lengthwise of the machine with their respective head stocks both when gripping or releasing a barrel shell and also when adjusting the head stocks to suit different lengths of barrel shells while at the same time always maintaining a driving connection between the gear 4wheels and the driving shaft.

The cutter mechanism whereby the crozes, chamfers and ends of the barrel shells are cut on the staves of the 'barrel shell may be variously constructed but in the preferred form shown in the drawings these, cutter mechanisms are constructed and operated as follows:

Arranged adjacent to the outer side of each head stock is a main cutter lever which swings in a vertical plane and preferably comprises an inner section 91 and an outer section 92. The inner section 91 is pivoted at its inner end to the adjacent head stock by a bolt 98, andthe outer end of the inner section 91 is pivotally connected with the inner end of the outer section 92 by a pivot bolt 94. On each of the inner lever sections 91 is arranged a Vbearing 95 whose axis is arranged horizontally and in this bearing is adjustably secured a short cutter arbor 96 which is held in place by splitting the bearing 95 and connecting the parts thereof by' a clamping screw 97.

On the inner end of this arbor is arranged a cutter head or holder 98 which carries a crozing blade or cutter 99 which is adapted to cut the croze in the bore of the adjacent end of the barrel shell, and a chamfer cutter or blade 99a which is adapted to cut the chamfer on the corresponding end of the bore of the barrel shell, and a shoe 100 which operates to prevent the chamfer cutter from entering the wood of the barrel shell too deep. This croze and chamfer cutter and the guard shoe are mounted on one side of the center of the cutter arbor 96 so that upon swinging the holder above the aXis of this arbor, the cutters 99, 99a and the'shoe 100 may be adjusted relative to thebarrel shell which is to be cut. For the purpose of enabling the cutters to be adjustedin accordance with the size of the barrel, the

thiclmess of the material which is being operated upon and the character of the material, the inner and outer sections of the cutter lever are adjusted relatively to each other. As shown in Figs. 5 and `7 this adjustable connection consists of two adjusting screws 101, 101 arranged in threaded openings in the outer lever section 92 on opposite sides of the pivot bolt 94 and bearing against the inner lever section 91 on opposite sides of said pivot bolt. Upon looseningone of these screws and tightening the other the relative position of the inner and outer lever sections may be adjusted as desired and the cutters 99, 99a

`and the guard shoe 100 on the inner lever section may be brought into the desired position relatively to the barrel shell which is to be operated upon. i

Before a barrel shell is gripped by the chuck rings the cutter heads are swung inwardly so that the blades of the cutter heads are clear of the path of the barrel shell, but after the barrel shell is gripped by the chuck rings the cutter levers are swung outwardly so as to engage the croze and chamfer cut* ters and the guard shoes against the adjacent end portions of the bore of the barrel shell ,whereby the latter during its rotary movement with the chuck rings will be operated upon by the cutter mechanism so that the Croze cutters and the chamfer cutters will produce the crozes and the chamfers at opposite ends of the bore of the barrel shell. Afterthis cutting operation has been completed during at least one rotation of the barrel shell the cutter levers are again swung inwardly so as to retract the cutters and guard shoes from the bore of the barrel shell.

This rocking motion of the cutter levers is effected automatically by motion derived from the main driving shaft and is preferably effected by the following means:

102 represents vertically swingingcam levers arranged transversely underneath the lower part of the main frame and each pivoted at one end to this frame while its opposite side is constructed in the form of a fork and carries a horizontal longitudinal coupling rod 103. 1011 represents upright shifting rods each sliding with its intermediate part vertically in guide lugs 105 projecting laterally from the adjacent part of the companion head stock while its lower end is provided with a coupling head 106 capable of sliding lengthwise on the companion coupling rod 103 but compelled to move vertically therewith. The upper end of each shifting rod is connected with the outer end of the outer cutter lever section 92, as shown in Figs. 5 and 7. Each cam lever 102 is yieldingly held in its elevated position so that the croze and chamfer cutters and the guard shoe associated therewith are' in their retracted or inoperative position, this yielding vineans consisting preferably of a spring 107 bearing at one end against-,a shoulder 108.011` the main frame while its opposite end bears against a shoulder 109 formed on a lifting rod or bolt 110 connected with the lever 102, as shown in Figs.` 5 and 7. The downward movement oflthe cam lever 102 for the purpose of swinging the croZe and chamfer critters andthe guard shoe into their operative position relative to the bore shell is effected by means of a cam 111 arranged on the cam shaft. 51 and bearing against a roller 112 on the adjacent part of this lever, as shown by'dotted lines in Fifrs. 5 and 'Tand by full lines in Figs. 3

rock lever 102 due to the coupling head 1.06.v

being capable of moving lengthwise on the coupling rod 101 it is possible to shifttthe head stock and the parts mounted `,thereon including the internal cutter mechanism of which the blades 99, 99aform a part without disturbing the connection between the means which shift these blades into and out of their operative position andthe yshaft 51 from which motion is received.

In order to permit of definitely determining the depth of the cut of the croze and chamfer cutters notwithstanding the adjustability of the same without interfering with. the throw of the cam 111, the outer section 92 of the main cutter lever is arranged to engage a fixed stop 200 at the end of its operative, movement and a yielding connection is provided in the means which operate this lever by motion derived from the cam 111 so as to avoid injury to the cutters or other parts during the excess throw of the cam 111 after the lever section 92 engages the stop 200. This yielding provision is preferably arranged between the upper end of the shifting rod 101- and the outer lever section 92, and as shown in Figs. 11, 5 and 7 the same preferably comprises. a guide sleeve 112 pivoted on the outer end of the outer lever section 92V and receiving the upper part of the companion shifting rod 104, a shoulder 113 consisting preferably of screw nuts arranged on this shifting rod and bearing against the underside of this coupling sleeve, and a spring'lM bearing at one end against the upper side ot' this coupling sleeve and at its other end against ayshoulder 115 whichlatter is prefer ably formed bv screw nuts on the adjacent part of the shifting rod 104. By this means a downward motion of the cam lever 102 produced by the cam 111 will cause the croie and chainfer cutters to swing outwardly against the bore of the barrel shell and effect their cutting operations in a normal Leeft-,vae

manner until the lever section 92 engages the stopllZQQ.- Thespring 111 is sufficiently stiff.

are moved into and fout of ,their operative position an endut/ter l116 -is in oved; into and out .of-iengagement with the respective end of thebarrel "shell forthe .purpose of trinr. ming the correspunsding ends of the staves unifOrmlyand evenly. This end cutteris mounted on a verticallyswinging auxiliary cutter arm 1171whiclris'pivotediby means of a horizontally ylongitudinal pinllSon a bracket-119 whichis adjustable radially on the outer side of the respective head stock.

by means of a clamping bolt 120secured to this head stock: and passing through a slot 121 in said bracket, as shownin Figs. 4 ,and 5. The end cutter is preferably operated by means of ashifting rod122 -pivotally connected at one end with. the` outer end of the adjacent cutter lever, a shoulder 123 yon the shifting rod 122 consisting preferably of a screw nut and bearing againstpne sideoitl the end cutter armf117, anda spring12 l bearing at one endagainst the opposite side of this cutterarmfat its opposite en d against a shoulder 125 vformed on the shifting'rod 122 preferably by a screwA nut thereon.` As the 'cutter llever is pulled downwardly for moving the croze andl chamfer cutters into their operativeposition the shiftin rod 4122 and spring 124 voperate to pull' the end cutter arm iiiwardlyV so that the end cutter` moves acrossthe adjacent edge of thebarrel staves and trims the same oifl evenly. Owing to the employmentffof the spring 1211 the engagement of the -end Lcutter is not positive but permits this end cutter to adapt itselfto the characterfof'the material which is being operated upon. During the return stroke of the main cutter lever, the shoulder 123 of the -shifting rod V 122by engaging withthe end cutterarm 117 turnsfthe latter back;

wardly andV retracts the xendmitter out of the path ofthe barrel shellg'preparatory"to engaging the Astaves of the neXtb'arrel shell whichI is to be operated upon.

While the barrel shell-is beingxmoved for Hardly bythefeed beltand until it `reaches the seats 12 of the guide rails A11`the same is free ,but after the -cutting operation 'only the saine has beencompletedthe same is en-` gaged by a retainingdeviee so as tostopthe rotation of the barrel shell preparatory to beingadvanced to the'hoopstripping mechanism. In its preferred form this retaining or holding device comprises two vertically movable curved j awe 126 which are adapted to move toward and from the upper side of the barrel shell. These two holding or retaining jaws are mounted on the front ends of two rock arms 127 which are connected at their rear ends with a horizontal longitudinal rock shaft `128 journaled in bearings 129 arranged on the upper ends of the rear posts 16, as shown in Figs. 3, 4, 5, 6 and 7 rPhe rocking motion of the shaft 128 is preferably derived from the rotary cam shaft 51 by means of a holding cam 130 arranged on this shaft and engaging with a roller 131 on a holding lever 132'pivoted on the underside of the main frame to swing vertically, as best shown inFig. 5, and operating to de0 press this lever, yielding means for elevating this lever comprising a( spring 133 bearing atone end against a shoulder 134 on the main frame and against a shoulder 135 formed on a rod 136 connected with the lever 132 and a shifting rod 137 connected at its lower end with the holding lever 132 and at its upper end with arearwardly projecting arm 138 on the rock shaft 128'. When a barrel shell or body is.being advanced from the front end of the guide rails 11 by the carrying belt toward the cutting position, the jaws 126 are in their elevated position and out of the path of the barrel shell and after the cutting operation on the shell has been completed these two holding or retaining jaws descend and engage with the upper side of the barrel shell on opposite sides of its bilge, as shown in Fig. 8, thereby stopping rotation of the barrel shell and permitting of advancing the same properly tothe hoop stripping mechanism.

After the barrel shell which has just been cut advancesV one step from the cutting position the same is held by a rear holding device in the proper position on the supporting rails and engaged by mechanism which operates to remove or strip off the temporary hoops fro-m opposite ends `of the respective barrel shell. During this forward step of the barrel shell after the cutting operation on the same has been effected the advancing side of the barrel shell engages with two yieldable stops consisting preferably of two vertically swinging stop levers 139 pivoted on the delivery portions of the 'rails 11 by means of pins 140 so that one arm of each lever projects upwardly into the path of the barrel shells while the lower arm thereof projects downwardly. The latter is connected by means of a spring 141 with a downwardly projecting bracket 142 on the adjacent guide rail which spring Operates to turn the upper arm of the stop lever forwardly and hold the same yieldingly in an upright position against a stop 143 on the adjacent part of the respective guide rail. As the barrel shell engages or nearly engages the stop levers 139 the same is also engaged on the upper side of its bilge or central part by means of a vertically movable rear curved holding or retaining jaw 144 which is arranged on an arm 145 projecting rearwardly from the rock shaft 128. This rear holding jaw is in its elevated position while the barrel shell is moving from the cutting position on the guide rails 11 to the hoop stripping position and when it reaches the last mentioned position on the guide rails the rear holding jaw descends and presses with its curved face or concave unde side against the convex upper side of the bilge of the barrel shell and holds the same in place against movement in the direction of the axis of the barrel while the temporary hoops are being stripped from opposite ends of the latter. This hoop stripping mechanism is best shown in Figs. 2, 3, 4, 5, 6, 7 `and 8 and as there shown the same is constructed as follows:

146, 146 represent two strippingjaws which receive a combined vertical and longitudinal movement for the purpose of engaging these jaws with the inner'edges of the temporary hoops of the barrel shells on the upper sides of the latter, then moving these jaws lengthwise in opposite directions for the purpose of stripping the temporary hoops from the barrel shell and then again raising these jaws preparatory to moving the samein an elevated position and dropping them behind the inner edges of the temporary hoops of the'neXt following barrel shell. The means whereby this motion is imparted to these stripping jaws comprises two longitudinal stripper bars 147 which carry the stripping jaws on their opposing inner ends, two rock levers 14S pivoted to swing substantially in a horizontal plane and having their rear arms connected with the outer ends of the stripper bars while their front ends are operatively connected with the yolres 74 by providing the latter with loops 149 into which the front arms of the rock levers 143 project, as shown in Figs. 4, 6 and 8 and two lifting arms 150 projecting rearwardly from the rock shaft 128 and provided at their rear ends with eyes 151 which receive the stripper bars 147 between. their inner and outer ends. As the yokes 74 move away from each other together with the head stocks after completing the cutting operation on a barrel shell the front arms of the rock levers 148 move in the same direction, thereby causing their rear arms to move toward each other together with the stripping bars and the stripping jaws connected therewith. During this movement the stripping jaws are elevated by reason of the rock shaft 128 being turned at this time in a direction for also elevating the rear holding jaw 144. At the end of this separating movement of the yokes and head stocks and the approaching,movement of the stripping jaws the latter are arranged above the path of' the barrel shell and in such position that the faces of these stripping ,jaws are arrangediinside oflthe path of the temporary endihoops of thebarrelshell. After the barrell shell comesto rest in the yhoop strip.-

pingpvosition. and another barrel shell has reached the cutting position the rocking movement ofthe, shaft'128 causes the rear jawsll-lto engage the bilge of the barrel shell at the stripping, position and also causes thestripping bars :1417 to belowered so that ltheir Vjawsllaqare lowered upon the top, of :they barrel shell ata point between thev bilgemf the. barrel and the, opposing innera edgesofthetemporary hoops. As the yokes andthe head stocks thereafter.approach each otherforchuckinga lbarrel shell in the cutting, position thecorresponding outward or separating movement of the stripping jaws which occurs at thistime causes the latter to engagdthe. innerK` edges of the temporary hoops on the barrel shell and pull the same from opposite ends. thereof. These tempo,-`

rary hoops drop on the adjacent part of the floor or may be otherwise disposed of to-be,

used over again After v the temporary hoopshave been. thusstripped from the ends ofthe barrel shell the latterfis released by theraising of therear holding, jaw '144 and the stripping jaws are simultaneously raised by the lifting arms 150 preparatory to being againmoved toward each other in `an elevated position for engaging the hoops of the next following barrel shell.

The cutting and hoop stripping operations having been now completed. on the barrel shell the latter during its next forward stepl under ,the action of the carrying jaws of the propelling belt will press the yielding stops 139 downwardly out of the path of the barrel shell and cause the latter to be discharged from the machine.

In, adjusting the machine for dilferent sizes of barrel shells it is desirable at times to disconnect the cam shaft 51 from the driving shaft 52 for the purpose of permitting of the rotation of the chuck rings without operating. the barrel shell feeding and cutting, hoopstripping and other mechanisms in order to enable the attendant to adjust the cutter mechanism to the particular barrel shell which isto be operated upon. For this purpose a clutch is provided which is preferably interposed between the driven gear wheel 59 and the cam shaft 51 and preferably comprises a clutch sleeve 152 splined on the cam shaft 51 so as to be compelled to turn therewith but be free to slide lengthwise thereon and provided with a jaw or clutch tooth 153 adapted to be engaged with and disengaged from a corresponding clutch jaw or tooth 154 on the adjacent part of the drivengear wheel 59, as best shown in Fig. 6.
